Description
PACKAGING MATERIAL WITH HOLOGRAPHIC PATTERN.
This invention relates to a flexible sheet material fo use in packaging food products, particularly dry food product such as crisps, biscuits, nuts and cereals for example.
This invention particularly relates to sheet packagin material which incorporates holograms for decorative purposes.
Sheet packaging material for food packaging i conventionally supplied in roll form, in widths typicall between 650 mm and 1200 mm. These are considerably wider than conventional techniques allow for the production of sheet material embossed with holograms: for this purpose, a thermoplastic substrate is heated, impressed with an embossed platen and then cooled; but in order to ensure that an embossed relief pattern of the required uniform high quality is formed across the full width of the sheet material web, this web has been limited in width (typically to 200 mm) .
In accordance with this invention, there is provided a method of forming a flexible sheet material, comprising forming a thermoplastic layer over a substrate, then forming a holographic embossed relief pattern in the surface of the thermoplastic layer.
We have found that with the thermoplastic layer carried by a substrate, it is possible to achieve a uniform high quality relief pattern across webs of substantial width, e.g. up to 1200 mm. The thermoplastic layer may comprise an acrylic or a polyurethane. When heated, the thermoplastic layer softens and can then be embossed under light pressure from an embossing platen.
The thermoplastic layer may be applied to the substrate in the form of an aqueous-based or solvent-based emulsion or lacquer and then dried. If solvent-based, solvent is selected which is free of any toluene or methylethylketone, and which has a very low vapour pressure so that most, if not all, of the solvent is driven off during the drying of this layer. One suitable solvent is ethylacetate.
Printing may be applied to the embossed surface of the thermoplastic layer, preferably after a metal (e.g. aluminium) film has been applied e.g. by vapour deposition or sputtering.
The printing is preferably protected by a layer of varnish.
Alternatively, a separate sheet material may b laminated to the embossed thermoplastic layer, this separat sheet comprising a transparent substrate having printin applied to its undersu face.
Also in accordance with this invention, there i provided a flexible sheet material which comprises a substrat carrying a thermoplastic layer which is formed over its oute surface with an embossed holographic relief pattern. Further in accordance with this invention, there i provided a package formed of the above-defined flexible shee material and containing foodstuff.
Embodiments of this invention will now be described b way of examples only and with reference to the accompanyin drawings, in which:
FIGURE 1 is an enlarged diagrammatic section (not to scale) through a first embodiment of flexible sheet packaging material in accordance with this invention;
FIGURE 2 is a similar diagrammatic section through a second embodiment of flexible sheet packaging material in accordance with this invention;
FIGURE 3 is a similar diagrammatic section through a third embodiment of flexible sheet packaging material in accordance with this invention; and FIGURE 4 is a similar diagrammatic section through a fourth embodiment of flexible sheet packaging material in accordance with this invention.
Referring to Figure 1 of the drawings, there is shown a first embodiment of flexible sheet packaging material in accordance with this invention, the sheet material comprising a plastics film substrate 10 carrying a thermoplastics layer 14 which is embossed with holograms at intervals across its surface. The construction includes other layers which will be apparent from a description given below of the manner in which the flexible sheet packaging material is made.
Firstly, the film 10 is provided in sheet or preferably roll form, comprising polypropylene of typically 30 to 40 microns thickness. The film 10 is subjected to a corona discharge treatment over both of its surfaces, as indicated at
9 and 11. Next a keying or priming coating 12 is applied, e. of polyurethane. Then the thermoplastic layer 14 is applie in the form of an aqueous-based acrylic emulsion which is th dried. The sheet material so far prepared (comprising laye 10, 12 and 14) is then passed lengthwise through an embossi apparatus, in which it is warmed to soften the thermoplast layer 14, then impressed by a holographic master to fo holograms embossed in relief in the surface of the layer 14 and then cooled to preserve the embossed relief pattern. Thi embossed relief pattern is indicated at 15.
Next a film 16 of metal (typically aluminium) i deposited over the embossed thermoplastic layer 14, either b vacuum deposition or by sputtering. Then printing is applie to the sheet material over the film 16, and covered by a thi film of varnish, indicated at 17. The opposite surface of th sheet material is coated with a conventional cold seal laye 8.
The embodiment shown in Figure 2 comprises polypropylene film substrate 20 of typically 18 to 24 micron thickness, with heat seal layers 19,21 co-extruded with th substrate over its opposite surfaces. One surface is the subjected to a corona discharge treatment, as indicated at 22 then the thermoplastic layer 24 is applied, in the form of solvent-based polyurethane. Once this is dried, the layer 2 is formed with an embossed relief pattern 25, as described wit reference to Figure 1 and given an aluminium film 26. Th sheet material may then be printed over the film 26 and coate with varnish, also as described with reference to Figure 1
Alternatively however, the sheet material so far described ma be laminated to a separate material which comprises transparent polypropylene layer 20a having a heat seal laye
21a over one surface and a priming coating 22a on its othe surface: printing is applied over the coating 22a and the this surface is coated with adhesive 23a for bonding to th aluminium film 26. The printing may instead be applied to th film 26 before the bonding takes place. The printing i visible through the transparent layer 20a and the holograms ar visible through this layer, through the printing (or throug non-printed areas between printed areas) and through th
aluminium film 26.
The embodiment shown in Figure 3 comprises polypropylene film substrate 30 of typically 30 to 40 micron thickness with an acrylic heat seal layer 32 over one surfac and an acrylic thermoplastic layer 34 over the other surface
An embossed relief pattern, indicated at 35, is formed in th layer 34 in the manner previously described, and then th aluminium film 36 is applied. The sheet material is the printed over the film 36 and coated with varnish , also a previously described.
The embodiment shown in Figure 4 comprises polypropylene film substrate 40 coated over one surface with a pvdc heat seal layer 41 and over the other surface with an acrylic primer 42 to which an acrylic solvent-based thermoplastic layer 44 is applied.
The layer 44 is embossed at 45 and then receives an aluminium film 46 as previously described: as described with reference to Figure 2, the material may then be printed and coated with varnish, or laminated to the separate material consisting of layers 20a to 23a. In the former case the polypropylene substrate 40 has a thickness of 30 to 40 microns, whilst in the latter case the polypropylene substrates 40 and 20a each has a thickness of 18 to 24 microns.
The packaging materials which have been described provide an effective moisture and vapour barrier and is therefore for packaging foodstuffs, such as those mentioned previously herein. In forming a package, the sheet material may be folded to bring one side into contact with itself, or with the opposite side, and the contacting areas are sealed by the application of heat and pressure (if the contacting layers comprise heat seal layers) or pressure alone (if the contacting layers comprise cold seal layers) . In any event the package is formed with the embossed surface of the thermoplastic layer facing outwardly. As previously described, the thermoplastic layer of each embodiment is applied to the substrate in the form of an aqueous-based or solvent-based emulsion and then dried. If solvent-based, a solvent is selected which is free of toluene or methylethylketone, or at least such that after drying the
thermoplastic layer contains no more than lOmg^per square metr of retained toluene or methylethylketone.
